STENCILING' METHOD.

Application filed September 15, 1927. Serial No. 219,612.

This invention relates generally to stenciling methods, and has morearticular reference to a device for stenciling silk material or thelike.

The invention has for an object the provision of a device of the classmentioned which is of simple durable construction, ef ficient inoperation, and which can be manufactured, and sold at a reasonable cost.

The invention consists in providing a wooden table having a layer ofconcrete thereon covered by a piece of felt. A covering of oil clothrests upon the felt and a canvas on top of the oil cloth and the sllkmaterial or other equivalent material to be" stenciled is laid upon thecanvas. Frames are next provided and bolting cloth commonly used inmilling, pulp and flour mills for screening is secured tightly acrossthe bottoms of the frames. Negatives of the designs to be stenciled areformed on this bolting material, suitable margins being pro vided on thebolting material near the edges of the frames. The frames are providedwith means for adjusting their positions so that registering ofstenciled work is possible.

Dye and gum material suitably mixed is placed on the top of the paintedpart of the bolting material and a roller with an associated scraper ismoved over the bolting material, forcing thedye mixture through theunpainted part of the material and onto the silk, the frames having beenpreviously placed on the silk.

For further comprehension of the invention and the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawings, and to the appended claimsin which thevarious novel features of the invention are more particularly set forth.

Referring to the accompanying drawing,

. of the aperture.

Fig. 7 is a side view thereof, with the roller hanging downwards.

Fig. 8 is a vertical sectional View taken on the line 88 of Fig. 2.

The reference numeral 10 indicates generally a wooden table topsupported bylegs llconnected by braces 12. One side of the tabletop isprovided with vertical side 13 having a plurality of pins 14 clamped asat 1 1 on the said side and secured thereto by thumb screw 14. A layerof concrete 15 is secured to the top of the table, and felt material 16is attached to the top of the concrete. Oil cloth 17 is secured to thefelt 16, and canvas 17 is placed on top of oil cloth 16. SilkmateriallS, to be stenciled,

rests upon the canvas.

Frames 19 have a screen cloth generally used by flour and pulp millsknown as bolting cloth 20 secured across their bottoms by nails 2O whichare driven into the frame 19 through the reenforcededging20. Paintedportion 21 forming a negative of the design to be stenciled is on thebolting cloth.

Setting screws 22 are screwed in the side walls of frames 20 and areplaced adjacent the vertical side 13 oftable 10. By means of screws 22,the angle of the frame may be adjusted as desired with respect to theside of the table. I V

The frames 19 have brackets 23 attached to the tops thereof. Each of thebrackets is formed with a central aperture 2 L. At one end a slot 25connects with the aperture, and a bushing 26 is forced into the otherend An L-shaped member 27 has one arm projecting from slot 25, andthe-other slidably in aperture 24. A screw 28 is rotatably connected tothe last men tioned arm, as at 29, and this screw threadedly engages thebushing 26, and the free end of the screw has a slot 30. A turning toolmay be engaged in slot 30, and the screw 28 turned so as to move theL-member. The projecting arms of the L-members abut against the pins 14'to hold the frames against displacement, and the relative position ofthe frames to the pins 14, or directly stated, the relative positions ofthe frames 19 to the silk material 18 may be changed and adjusted byturning screws 28.

A roller and scraper 3O used in conjunction with the device consists ofa pair of brackets 31, each being formed with a pair of oppositeabutments 32. The brackets 31 are attached to the ends of a board 33, or

aluminum plate, formed with a bottom scraping edge 34. Links 35 arepivotally connected to the brackets and a roller 36 is connected betweenthe links. The links 35 and the abutments 32 are so arranged that theroller 36 may be on one side of the board 33 with the links against theabutments as shown in full lines in Fig. (5, or on the opposite side ofthe board with the links against the opposite abutments as shown bydot-dash lines 37.

The operation of the device consists in applying ink, or like on theroller 36, and then manually working the roller and scraper 30'' backand forth on the material 20 until the ink is forced through theunpainted part of the material 20 onto the silk 18. The roller 36 shouldpreferably be of a rubber compound. or may be made of any suitablematerial, but it instead of silk 1S, carpet or velvet is to bestenciled, the roller should be covered with felt. A steam line 38 maybe provided to aid in drying the stenciled material. One color isstenciled at a time, and when one color has dried, the frame may bereplaced with other frames holding the stenciling negatives of the nextcolor. The frames may be properly registered by adjusting screws 23 sothat the arms of L-mem hers L T abut the pins 14.

\Vhile I have illustrated and described my invention with some degree ofparticularity, I realize that in practice various alterations thereinmay be made. I therefore reserve the right and privilege of changing thedetails or otherwise altering the arrangen'ient of the correlated partswithout departing from the. spirit or the scope of the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by United States Letters Patent is:

1. In a device of the class described, the combination with a table forsupporting material to be stenciled and provided with a vertical memberwith clamps and projecting pins of tames for supporting stencils ofbolting cloth and arranged for engaging upon the table, brackets securedto the frames and having a central aperture communicative with an endslot, L-members slidably mounted in the apertures and having one armprojecting from the said end slots and arranged for engagement againstthe said pins for registering the frames relative to the table, bushingsengaged in the said apertures, and screws threadedly engaging in thebushings and rotatively connected with the L-members.

2. In a device of the class described, the combination with a table forsupporting material to be stenciled and provided with a vertical memberwith clamps and projecting pins of frames for supporting stencils andarranged for engaging upon the table, brackets secured to the frames andhaving a central aperture communicative with an end slot, L-membersslidably mounted in the apertures and having one arm projecting from thesaid end slots and arranged for engagement against the said pins forregistering the frames relative to the table, and a. means for adjustingthe positions of the L- mcmhers relation to the said brackets.

3. In a. device of the class described, the combination with a table forsupporting material to be stenciled and provided with a vertical memberwith clamps and projecting pins of frames for supporting stencils andarranged for engaging upon the table, brackets secured to the frames andhaving a central aperture communicative with an end slot, L-membersslidably mounted in the apertures and arranged for asraunint! variousfixed positions and having one arm projecting from the said end slotsand arranged for engagement against the said pins for registeringtheframes relative to the table.

4. A. registering device, comprising a bracket arranged for connectionon a frame, and having a central aperture col'nn'iunieatire with an endslot, and L-memhers slidahly mounted in the aperture, and arranged forassuming various fixed positions, and having one of its arms projectingfrom the said end slot and capable of engagement with a positioning pinfor registering the bracket relative thereto. i

In testimony whereof I have afiixed my signature.
